Before and during Salesforce's Dreamforce in SF

Updated 4:27 pm, Friday, September 21, 2012

If you were in the South of Market area anytime this week, you probably saw some of the thousands of people wearing blue Dreamforce badges walking around. And if you tried to drive in the area, you were probably caught in the traffic jams caused by the street closures.

Salesforce.com transformed the area in and around the Moscone Convention Center this week for the 90,000 people who attended the company's annual Dreamforce convention, which wrapped up Friday.

Here are photos that the San Francisco enterprise software company took before and during the conference that provide a rare look at how the convention center changes. You can move the interactive slider bar in the middle of these photos, or click "before" or "after."

The transformation was particularly dramatic on Howard Street, which was closed to traffic between Moscone North and Moscone South to allow Salesforce to create an outdoor park where attendees could eat lunch and relax between sessions. They also were able to play chess with three-foot-high pieces, help stuff emergency supplies in bags to be distributed to the needy and pedal stationary bicycles to recharge their cell phones while getting some exercise.
